Cusco LSD Type-RS Rear 1.5-way (1.5/2-way) Mitsubishi Lancer Evo IV/V/VI (CN9A) w/ MT (AYC Models)

Cusco is well-known for making high-performance drivetrain components, especially for rally and track cars. This Type-RS rear limited slip differential (LSD) is a prime example, built specifically for the Mitsubishi Lancer Evolution IV, V, and VI models (CN9A) equipped with a manual transmission and the Active Yaw Control (AYC) system. If you're looking to significantly improve your Evo's traction and handling, especially during spirited driving or on the track, this LSD is a serious upgrade.

The Type-RS is a 1.5-way LSD, meaning it applies locking force during both acceleration and deceleration, but with a stronger bias on acceleration. This design helps put power down more effectively when you're on the throttle, while still providing stability during corner entry and exit. It's a popular choice for drivers who want a noticeable improvement in grip and a more predictable feel from the rear end. The internal components are made from durable materials designed to withstand the demands of performance driving, ensuring consistent performance over time. Installation involves replacing the factory differential, and it's crucial to ensure proper setup and break-in procedures are followed according to Cusco's guidelines for optimal performance and longevity.

This LSD is designed to work with the AYC system on your Evo, integrating with the car's existing electronic controls for a refined driving experience. While installation requires mechanical expertise, the result is a substantial enhancement in how your Evo handles power and corners. You'll want to ensure you have the correct gear oil for LSDs, as specified by Cusco, to maintain its performance and durability.
